[ns] Poor validation issue...

["merlin.jiang" <merlin.jiang@msa.hinet.net>]

Hi all there,
    After browsing almost all archives
discussing tons of different validation
problems, still couldn't I solve what
I faced. I got -g turned on during compilation,
Perl5.6.1 installed (twice), paths set up,
$PATH order re-arranged, symbolic link built,
$PERL set, and executable perl placed
everywhere it could be, but the validation
failed all the time. Below is the message:
(command line: ./test-all-tcp)

[...]
../../ns test-suite-tcp.tcl ecn

ns: _o4 cleanup file5 ecn_(one_with_ecn,_one_without): usage: getrc -s node1 [options] [trace file...]

get trace files that match certain criteria related to source, dest or flow-id

options:
        -o outfile      write subset trace to output file
        -b              bi-directional, i.e. gather lines 
        -d node2        specify destination
        -f flowid       specify flow id
    while executing
"exec $PERL ../../bin/set_flow_id -s all.tr |  $PERL ../../bin/getrc -s 2 -d 3 |  $PERL ../../bin/raw2xg -s 0.01 -m 90 -t $file > temp.rands"
    (procedure "_o4" line 3)
    (TestSuite finish line 3)
    invoked from within
"$self finish $testname"
    (procedure "_o4" line 11)
    (TestSuite cleanup line 11)
    invoked from within
"_o4 cleanup file5 ecn_(one_with_ecn,_one_without)"
Test output differs from reference output
[...]

    Then I can't figure out where actually 
the problem is, nor can I understand what it means.
I hope that somebody who met this before but had solved it
can give me some hints. Thanks!
